Portal Hypertension01:22

Portal Hypertension

50
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...

Hepatic Portal System01:21

Hepatic Portal System

8.2K
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Esophageal Varices-I: Introduction

2.4K
Esophageal varices are dilated, tortuous veins which are found mainly in the submucosa of the lower esophagus but which may also appear higher up or extend into the stomach. They develop due to increased pressure in the portal venous system, often as a result of liver cirrhosis. This condition scars and damages the liver, impeding normal blood flow through the portal vein. To compensate, blood seeks alternative pathways, forming fragile new vessels (varices) in the esophagus and stomach. These...

Hepatic Encephalopathy01:29

Hepatic Encephalopathy

53
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...

Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

884
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Veins of the Abdomen and Pelvis01:18

Veins of the Abdomen and Pelvis

2.2K
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...

Summary

Symptomatic large portal vein aneurysms (PVAs) require surgical intervention. This case highlights a successful surgical repair using an aneurysmorrhaphy and prosthesis, followed by radiological treatment for an early complication.

Area of Science:

  • Vascular surgery
  • Interventional radiology
  • Gastroenterology

Background:

  • Portal vein aneurysms (PVAs) are rare vascular anomalies.
  • PVAs are typically asymptomatic and found incidentally.
  • Symptomatic PVAs or those with associated pathology warrant treatment.

Observation:

  • A 75-year-old male presented with symptomatic, enlarging portosplenomesenteric aneurysms.
  • Interventional radiology was not suitable due to the large aneurysm size.
  • A two-stage surgical approach was selected.

Findings:

  • The surgical technique involved aneurysmorrhaphy followed by Goretex prosthesis placement.
  • An early complication was successfully managed with interventional radiology.
  • The patient remained asymptomatic six months post-surgery.

Implications:

  • Management of large PVAs presents surgical challenges regarding timing and technique.
  • A combined surgical and radiological approach can be effective.
  • This case underscores the importance of tailored treatment strategies for complex PVAs.
